1. Production Technology

Roto molding kayak

also known as rotational molding, rotational molding or rotary molding, is a hollow molding method for thermoplastics. The method is to add plastic raw materials into the mold first, then the mold is continuously rotated along two vertical axes and heated, and the plastic raw materials in the mold are gradually and uniformly coated and melted and adhered to the mold cavity under the action of gravity and heat. On the entire surface, it is formed into the desired shape, and then cooled and shaped to form a product.

Blow molding kayak

Also known as hollow blow molding, is a rapidly developing plastic processing method. The tubular plastic blank obtained after thermoplastic resin extrusion or injection is put into the split mold while it is hot (or heated to a softened state). Immediately after the mold is closed, the compressed air is passed into the mold blank, so that the plastic blank expands and closes to the inner wall of the mold, and various hollow products are obtained after cooling and demoulding.

Thermoforming kayak

A kind of plastic processing technology, the main principle is to heat and soften the flat hard plastic sheet, then absorb it on the surface of the mold by vacuum, and form it after cooling. It is widely used in plastic packaging, lighting, advertising, decoration and other industries.

2. Cost

Thermoforming kayak > Rotational molding kayak > Blow molding kayak

Roto molding kayak

The mold price is relatively cheap, and the product price is relatively high. It mainly produces hollow products, packaging products and super-large products. The shrinkage ratio is relatively large and the output is relatively low. Rotational molding products are relatively large. Plastic particles are put into the mold to heat, and then the mold is continuously rolled to make the plastic adhere to the inner wall of the mold.

The cost of the mold is lower than that of the mold, and it is relatively simple. The production cost of the article is also lower.

Lightest material – ABS and glued hull manually

3. Production Capacity

Blow molding kayak > Rotational molding kayak > Thermoformingkayak

Blow molding – 150-200 PCS/Machine/day

Roto molding – 15-20 PCS/Machine/day

Thermoforming molding – 5-10 PCS/day
